Do you spend endless hours online? Are you one of millions who can’t get enough of MySpace or Facebook?
Internet addiction is a "common" mental disorder and health officials need to recognize it as such, said Dr. Jerald Block in The American Journal of Psychiatry; it is being reported by news.com.au.
Block claims Internet addiction has three subtypes: excessive gambling, sexual preoccupations and e-mail or text messaging.
"Internet addiction appears to be a common disorder that merits inclusion in the Diagnostic and Statistical Manual of Mental Disorders," Block said in the journal.
Internet addictions have these components in common: excessive use, withdrawal, tolerance and negative repercussions, Block said.
Then, addicts develop a tolerance to a certain level of technology, making them want to upgrade software and hardware, he said in the Journal.
As a result of Internet addiction, people often suffer from social isolation and fatigue.
